What term describes the process of recording and transmitting the readings of an instrument?

The process of recording and transmitting the readings of an instrument is known as telemetry. This term is specifically used to describe the automatic measurement and transmission of data from remote locations. In telemetry systems, instruments collect data, which is then sent via various communication methods to a receiving system for monitoring and analysis. This is crucial in many applications, such as weather monitoring, spacecraft telemetry, and medical implementations, where remote data collection is necessary.

Data logging refers to the act of collecting and storing data over time, but it does not inherently involve transmission; it focuses more on the storage aspect. Signal processing relates to the manipulation and analysis of signals after they have been received, rather than the initial transmission of data. Communication is a broader term that encompasses the exchange of information but does not specifically refer to recording and transmitting instrument readings. Therefore, telemetry is the most precise term for this process.
